Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   38927   clinical trials with a EudraCT protocol, of which   6396   are clinical trials conducted with subjects less than 18 years old.
    The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Coronary Microvascular Dysfunction (CMD). In CMD, ischemia is caused by impaired endothelial and/or non-endothelial coronary vasoreactivity resulting in the coronary microvasculature not dilating properly or becoming vasospastic.
    E.1.1.1Medical condition in easily understood language
    In coronary microvascular dysfunction (CMD), the small vessels that provide blood and oxygen to the heart muscle do not function properly. In some cases they cannot relax, in other cases they spasm.
    Bij patiënten met CMD functioneren de kleine kransslagaders die de hartspier van bloed voorzien niet goed. Soms kunnen de vaten zich niet goed ontspannen, of soms verkrampen ze juist.
